Canara Bank — refund not processed or delay in refund

[28/02, 14:01] nikita tyagi: i ordered asus vivobook 14 x409fa-ek555t on 19th february 2020. The delivery boy didn't deliver the product and filed a request of return. So i talked to three different executives regarding the delivery of my product and they gave me assurance that i ll receive my product on 23rd february 2020. Instead of delivering my product, amazon initiated refund for the same. Refrence id of the transaction/refund is 74332740055005481380010

Its more than 4 working days and according to amazon's mentioned timeline i am supposed to receive the refund withing 4 working days.
They are asking me again and again to contact my bank account and i have done that several times already. Instead of helping me out, amazon is denying the fact that i haven't received the refund yet.
